Just been out to the garage to look at my 500, luckily the previous owner had kept the original boxes that the RHD must have came in ( I use them for storing my LHD lights). Both sets are Hellas.

I checked my lenses and the driving light on both my RHD & LHD sets are quite heavily fluted, so I'm not sure if this is exactly what you are after, but here are the codes anyway:-

Left hand headlight:-

001 129 583 ( marked on headlight )
1LJ 004 440 611 (marked on box)

Right hand headlight:-

001 129 584 ( marked on headlight )
1LJ 004 440 621 (marked on box)

Hope this is of some help to you.

Martin.
